Study Of Strength Parameters Of Graphene Based Concrete With Inclusion Of Industrial Waste (Cupola Slag)

Abstract

Aiming to compare microstructure and mechanical characteristics of conventional concrete with graphene reinforced concrete with 0.05% wt and partially replacement of Cupola slag as a fine aggregate concrete using Scanning Electron Microscope and various mechanical methods to identify effect of GO and copula on concrete. The effects of the GO content, w/c ratio and cupola on mechanical properties of GO and Cupola cement composites were thoroughly investigated through experimental tests. The testing results show that with constant w/c ratio and optimum 30% cupola as replacement of fine aggregate, compressive and spilt tensile of concrete surprisingly enhanced as compare to convectional concrete. The investigation of the composition–microstructure–strength relationship shows that the introduction of GO could help improve the macroscopic properties for the cement-based composites via improving the microstructure of cement hydration products, refining the crystal size, and forming a denser and more uniform network structure. The filling effect, hydration effect and nucleation effect of GO could be optimized with an appropriate combination of w/c ratio and GO content.
